Precautions for using Disposable Protective Face Shield

① Check all parts of the Disposable Protective Face Shield for obvious scars, cracks, scratches, or abnormal appearance.
②Check all parts of the Disposable Protective Face Shield to see if the screws are loose or fall apart.
③Because there is a gap between the protective mask and the face, the protective glasses can also be used with the protective mask.
④When working with the welding mask, in order to prevent the sparks from hurting the body, do not stop using it in the middle.
⑤When using fire and heat protection masks, check whether there is harmful light. If there is, use it together with light-proof glasses.
